vim Dockerfile

ADD ruby-3.2.2.tar.gz /data/
WORKDIR /data/ruby-3.2.2
RUN yum update -y \
&& yum install -y gcc openssl-devel libyaml-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel make
RUN yum install -y centos-release-scl-rh centos-release-scl
RUN yum install -y llvm-toolset-7-clang
RUN scl enable devtoolset-7 "./configure && make && make install"
make时会报错make: *** [miniinit.o] Error 1。在加入以下后，编译成功,其中./configure && make && make install需要放在scl enable devtoolset-7" "中运行，若放在下一行则新bash不生效，仍然用老bash
RUN yum install -y centos-release-scl-rh centos-release-scl RUN yum install -y llvm-toolset-7-clang RUN scl enable devtoolset-7 "./configure && make && make install"
